IVHRHOR ATTACHMENT FOR THEATER-CHAIRS.

SPECIFLCATION forming part of Letters Patent No. 700,975, dated May 27,1902.

Application filed January 30,1902. Serial No. 91,866. (No model.)

To (tZZ whom it may concern:

Beit known that I, HATTIE AGUSTA NORTH- RIDGE, a citizen of the UnitedStates, residing at Brooklyn, in the county of Kings and State of NewYork, have invented certain new and useful Improvements in MirrorAttachments for Theater-Chairs, of which the following is aspecification.-

All theater-goers feel the annoyance from the hat-wear, and while it hasbeen proposed to provide mirror-brackets adj ustabie on the backs ofchairs for holding the hats and observing persons in different parts ofthe house in rear of the occupant of the seat, so far as I know and canfind there is not such a convenience in use in any theater in thecountry, although such a convenience is admitted to be a desideratumfelt by every occupant of a seat in a theater.

Myimprovement is directed to the provision of such a conveniencedesigned with special reference to its simple construction, andparticularly in the provision of friction-joints whereby thehat-bracketis held in the desired position and the mirror when used assuch held in the position which the occupant desires for adjusting herhat or for seeing persons in the rear of her seat in any part of thehouse and in rendering the device safe as a fixture on the back of thechair. In these particulars my improvement will be set out in the claimappended hereto in connection with the accompanying drawings, in whichFigure 1 shows my mirrored hat-holding attachment in its folded positionagainst the back of the chair. Fig. 2 is a side view of the same asswung out from the back of'the chair for holding a hat or forobservation. Fig. 3 shows in side view, enlarged, the frictionalcoupling which secures the mirrored frame to the curved arm. Fig. 4 is atop view of the same. Fig. 5 shows such frictional coupling in verticaland horizontal sections. Fig. 6 is a top view of the frictional couplingof the arm with the chair-back, and Fig. 7 is a vertical section of thesame.

A bent or curved arm 1 pivotally connects and carries at one end amirrored frame 2 and at its other end is pivotally connected to the backof the chair, and my improvement resides in these connections, wherebythe arm and the mirror are free to be set in any position and held bythe frictional functions of their respective pivotal connections. Thecon nection of thearm to the chair-back is such as to provide freedomfor the horizontal swinging of the arm and for holding it by friction ofits joint connection in folded position against the back of the chair orin its outward-swing positions. At this connection the curved arm has adownward-return branch 3, which terminates in a short angle end 4, bywhich the arm is secured by a keeper 5, fastened to the chair-back. Thiskeeper is of sheet metal and engages the return-arm branch 3 like astrap and forms a tube, within which the arm is held and secured by itsshort angle end. The keeper is U shape in cross-section, its edges 6being turned outward from each other to form. clips, which engage theedges of an opening in a plate 7, which is secured to the back of thechair, and thereby secures the keeper to the plate. A plate-spring 8 isset in the opening in the plate and forms the back of the keeper andafrictional bearing or binder against the return-arm branch, the bendsof which prevent the removal of the arm from the keeper, while allowingit to freely swing in frictional contact with the plate-spring to holdthe arm in folded position against the chair-back or when swung out tohold the hat. At its other end the upward-standing end of the curved armhas an annular groove 9, and a tip tubular coupling or socket-stem 10 isfitted upon the grooved end andby protuberances or shoulders 11, formedon its inner walls, engage the groove, and thereby secures thesocket-tip or coupling to the arm and gives freedom for the coupling toturn or swivel upon and as a section of the arm. The upper end of thesocket-stem coupling is bifurcated to form jaws 12 to receive a bracketprojection 13, secured to the back of the mirror-frame, and to whichbracket projection the socket-stem is joined by a rivet 14 to allow avertical swinging movement of the mirrored frame. This rivet-joint,it.will'be noted, clamps the jaws of the socket-coupling upon thebracket projection to give sufficient friction to the clamped parts tohold the mirror in whatever position it may be set with a verticalmovement, while the groove-and-shoulder engagement of thecoupling-socket stem with the curved arm gives sufficient friction tohold the mirror when turned to either side or in any positionforobservation by the occupant of the chair of persons in the rear thereof.This construction of the joint connections gives the advantage ofholding the arm and the mirror in their set positions solely by frictionand avoids clamp-screws, which would permit the removal of the parts,and the cost of ball-and-socket joints for the mirror. The attachmentcan be secured to or near the edge of the chair-back.

Looking at Fig. 5 it will be noted that the interior locking of thecoupling stem or tip upon the arm is by indenting the outer walls of thetip to form integral protuberances on the interior of the walls of thestem at points coincident with the groove of the arm, whereby theadjustment of the stem is maintained and the stem rendered inseparablefrom the arm, while the rivet. connection of the mirror with the stemgives freedom for the adjustment of the mirror and renders itinseparable from the stem. c This inseparable feature of thejoints is amatter of importance in the use of mirror attachments fortheater-chairs,

which with screw-fastenings could be easily removed and lost.

I claim- An inseparable mirror attachment for theater-chairs and incombination with an arm pivotally mounted on the back of the chair toswing horizontally and having an annular groove at its other end, acoupling stem or tip having its lower end tubular and formed withintegral shoulders or protuberances on its interior walls frictionallyengaging or binding the groove of the arm to automatically maintain theadjustment of said stem, and a mirror-frame pivotally connected to theupper end of said coupling stem or tip, the pivot having its ends upsetto produce friction whereby the adjustment of the glass is main* tainedand the stem and the mirror rendered inseparable from each other andfrom the arm,

In testimony whereof I affix my signature in presence of two witnesses.
